And inventor has found under study for action, acquires voice when being provided with sound acquisition module in the first earphone and the second earphone
During being transferred to electronic equipment, while can also electronics be caused to set the noise transmission electron equipment in the environment of acquisition
The ascending voice that preparation is sent can carry more environmental noise, influence user experience.Therefore, inventors herein proposing can in the application
To reduce environmental noise, the method for speech processing, device and electronic equipment of user quality are promoted.
Present embodiments are specifically described below in conjunction with attached drawing.
Referring to Fig. 3, a kind of method of speech processing provided by the present application, is applied to electronic equipment, which comprises
Step S110: when the electronic equipment is on call, the electronic equipment is obtained in same a period of time
The first voice signal and the second voice signal received, first voice signal are acquired and are sent by the first earphone, institute
It states the second voice signal and is acquired and sent by the second earphone.
It is understood that can synchronize after the first earphone and the second earphone are in wearing state and receive user institute
The voice signal of transmission.So after the first earphone and the second earphone receive voice signal, the language that will can directly receive
Sound signal is sent to electronic equipment.So for electronic equipment in inscribed the first voice signal received of same a period of time and
Second voice signal is the identical signal of voice content.
Wherein, as a kind of mode, whether wearing can be in come test earphone by the infrared sensor that earphone is arranged
State.Wherein, it should be noted that when earphone is worn on human ear, partial region can be blocked, then
In this case, the mode for the region setting infrared sensor that can be blocked after earphone is in wearing state, passes through inspection
The state value of the return of infrared sensor is surveyed to determine whether the infrared signal of infrared sensor transmitting is blocked, so that it is determined that ear
Whether machine is in wearing state still non-wearing state.So it is understood that when the state value returned characterizes infrared signal
It when being blocked, determines that earphone is in wearing state, when the state value of return characterization infrared signal is not blocked, determines at earphone
In non-wearing state.
It is so used as a kind of mode, earphone can be characterized with the state value that the cycle detection infrared sensor of setting returns
Content, and the content transmission electron that the state value that returns of the infrared sensor that will acquire again with the period of setting is characterized
Equipment, so that electronic equipment records whether earphone is in wearing state in real time.Optionally, electronic equipment can be by building locally
It stands with text file, a variable is configured in this article this document, for example, headset_status.If electronic equipment identifies earphone
When the content characterization earphone passed back is in wearing state, variable headset_status assignment 1 can be given, and when electronic equipment is known
When the content characterization earphone that other earphone is passed back is in non-wearing state, variable headset_status assignment 0 can be given.So when
Electronic equipment detect be by earphone carry out audio broadcasting after, can be by detecting variable in this article this document
The value of headset_status determines whether earphone is in wearing state.
It should be noted that may be used also other than carrying out test earphone mentioned by infrared sensor and whether being in wearing state
To determine whether earphone is in wearing state by setting other elements.For example, can earphone wearing after with human skin
A component is arranged in the position of contact, and resistance value can change (for example, thermistor) after which contacts with human skin,
So in this case, which is arranged in an access, the curent change by detecting the access can determine
Whether earphone is in wearing state.Correspondingly, in this manner, when earphone determines that earphone is by the curent change of the access
It is no after the wearing state, the result that can be will test is sent to electronic equipment.
Step S120: the quality of first voice signal and second voice signal is compared.
It should be noted that, although the first earphone and the second earphone are issued in acquisition user in communication process
Voice content, still, directions question or the first earphone or the second earphone itself when due to user's sounding are set with electronics
The fine or not problem of communication quality between standby, although respectively entrained voice content be it is identical, electronic equipment is connect
The quality between the first voice signal and the second voice signal received has difference.For example, the first voice signal and the second language
Respectively entrained voice content is " ABCDEFG " to sound signal, still, may voice content entrained by the first voice signal
Intensity of sound can be greater than the intensity of sound of voice content entrained by the second voice signal.
It is so used as a kind of mode, the quality for comparing first voice signal and second voice signal
Step includes: the audio parameter that acquisition first voice signal and second voice signal respectively carry voice content；Base
In the audio parameter, the quality of first voice signal and second voice signal is compared.
Wherein, described to be based on the audio parameter, compare first voice signal and second voice signal
If the step of quality includes: that the audio parameter includes intensity of sound, first voice signal and second language are compared
The intensity of sound of sound signal, using the biggish voice signal of intensity as the preferable voice signal of quality；If the sound
Sound parameter includes sound continuation degree, compares the sound continuation degree of first voice signal and second voice signal, will
The higher voice signal of continuation degree is as the preferable voice signal of quality, wherein and discontinuous point is fewer in voice content,
The sound continuation degree is higher.
Wherein it is possible to understand, its sound-content carried of the signal bigger for intensity of sound being capable of better quilt
Conversation object is identified.So be conducive to be taken using the bigger signal of intensity of sound as the preferable voice signal of quality
The clearer voice signal of the voice content of band.Furthermore if the voice content carried in voice signal has discontinuous place,
It is desultory for so will cause the sound that user hears, then using the higher voice signal of sound continuation degree as quality compared with
A good voice signal is conducive to the more continuous voice signal of the voice content carried.
Step S130: the preferable voice of quality in first voice signal and second voice signal is believed
Primary input signal number as noise reduction process is believed a second-rate voice signal as the auxiliary input of the noise reduction process
Number.
It should be noted that being to do calculus of differences by primary input signal and auxiliary input signal during noise reduction process
To balance out respectively entrained noise signal.For example, can be subtracted by primary input signal auxiliary input signal obtain it is to be sent
Voice signal.And because of the noise signal approximation that the first earphone and the second earphone receive, then being subtracted by primary input signal
Auxiliary input signal is gone to obtain in voice signal to be sent, noise signal is cancelled out each other.
Based on foregoing manner, if a second-rate voice signal is directly used to subtract quality as primary input signal
A preferable voice signal, the opposite in phase of the voice signal not only resulted in and actual voice signal, so that
A phase change must be carried out before transmission.It is to believe first voice in this application so in order to avoid the problem
Number and second voice signal in primary input signal of the preferable voice signal of quality as noise reduction process, by quality
Auxiliary input signal of the poor voice signal as the noise reduction process.
Step S140: it is sent out by the voice signal of noise reduction process output as the ascending voice of the call
It send.
A kind of method of speech processing provided by the present application, working as, the electronic equipment is on call, obtains same
The first earphone received in time cycle acquires and the first voice signal sent and the second earphone acquire and send
Two voice signals first compare the quality of first voice signal and second voice signal, then by first language
Primary input signal of the preferable voice signal of quality as noise reduction process in sound signal and second voice signal, will
Auxiliary input signal of the second-rate voice signal as the noise reduction process, then will be by noise reduction process output
Voice signal is sent as the ascending voice of the call.So that during being conversed based on earphone, electricity
The voice signal for the identical content that first earphone and the second earphone acquire can be carried out mass ratio pair by sub- equipment, so as to subsequent
Noise reduction process during, by the quality higher one primary input signal as noise reduction process so that for be based on ear
Voice de-noising in machine communication process improves the clarity of ascending voice, and then the user experience is improved.
Referring to Fig. 4, a kind of method of speech processing provided by the present application, is applied to electronic equipment, which comprises
Step S210: when the electronic equipment is on call, the electronic equipment is obtained in same a period of time
The first voice signal and the second voice signal received, first voice signal are acquired and are sent by the first earphone, institute
It states the second voice signal and is acquired and sent by the second earphone.
When user is during carrying out voice communication, other sound sources have been likely present around user.For example, with
There are also other users to speak around family, or has other audio-frequence player devices playing audio.And for these other
Sound source, intensity of sound of the sound issued when may be transferred at the first earphone and the second earphone have biggish difference.
Step S220: the first intensity of sound of voice content entrained by first voice signal is obtained.
Step S230: the second sound intensity of voice content entrained by second voice signal is obtained.
Step S240: first intensity of sound and the second sound intensity are compared.
Step S250: if first intensity of sound and the second sound strength difference are not less than the given threshold,
Abandon first voice signal and second voice signal.
It should be noted that after the first earphone and the second earphone are in wearing state, although the first earphone and second
The intensity of the collected sound of earphone has difference, but as being closer.So in this case, electronic equipment than
Given threshold is less than to the first intensity of sound out and the second sound strength difference, then can be determined that the first voice signal and
The sound source of second voice signal is user, and if first intensity of sound and the second sound strength difference be not small
In the given threshold, issued then can be determined that and carry other more sound sources in the first voice signal and the second voice signal
Sound.
It is so used as a kind of mode, electronic equipment can be directly by the first voice signal and described the in this case
Two voice signals abandon.Alternatively, alternatively mode, from the first voice signal and second voice signal respectively
The voice voice signal that intensity of sound is less than the given threshold is isolated, as the voice signal of the first earphone actual acquisition,
And second earphone actual acquisition voice signal.It is understood that the voice signal of the actual acquisition is what user issued
Voice signal.
Step S260: if first intensity of sound and the second sound strength difference are less than given threshold, institute is compared
State the quality of the first voice signal and second voice signal.
Step S270: the preferable voice of quality in first voice signal and second voice signal is believed
Primary input signal number as noise reduction process is believed a second-rate voice signal as the auxiliary input of the noise reduction process
Number.
Step S280: it is sent out by the voice signal of noise reduction process output as the ascending voice of the call
It send.
A kind of method of speech processing provided by the present application, working as, the electronic equipment is on call, obtains same
The first earphone received in time cycle acquires and the first voice signal sent and the second earphone acquire and send
Two voice signals after getting the intensity difference between the first voice signal and the second voice signal away from setting value is less than, then compare
To the quality of first voice signal and second voice signal, then by first voice signal and described
Primary input signal of the preferable voice signal of quality as noise reduction process in two voice signals, by a second-rate language
Auxiliary input signal of the sound signal as the noise reduction process, then using the voice signal by noise reduction process output as described in
The ascending voice of call is sent.So that electronic equipment can be by first during being conversed based on earphone
Earphone and the voice signal of the identical content of the second earphone acquisition carry out mass ratio pair, so as in subsequent noise reduction process process
In, by the quality higher one primary input signal as noise reduction process, so that for based in earphone communication process
Voice de-noising improves the clarity of ascending voice, and then the user experience is improved.
Referring to Fig. 5, a kind of method of speech processing provided by the present application, is applied to electronic equipment, which comprises
Step S310: when the electronic equipment is on call, the electronic equipment is obtained in same a period of time
The first voice signal and the second voice signal received, first voice signal are acquired and are sent by the first earphone, institute
It states the second voice signal and is acquired and sent by the second earphone.
Step S320: the voice signal of the first direction based on first earphone and the voice letter of second direction
Number, obtain the source direction of the first earphone voice signal collected.
As a kind of mode, it can be provided with sound acquisition module in the multiple directions of the first earphone and the second earphone,
So as to acquire the sound of multiple directions simultaneously.Also, it is to be understood that be for same sound source issue sound, Duo Gefang
It is different to the collected intensity of sound of sound acquisition module institute being respectively provided with.For example, as shown in fig. 6, shown in Fig. 6,
Relative position between first earphone 110 and the second earphone 120 and user, it is to be understood that the first earphone 110 and
Two earphones 120 are worn at user's ear in actual use, and the relative position between them is only identified in Fig. 6, and
It is not used in the physical location of explanation the first earphone 110 and the second earphone 120.Wherein, the first side 111 of the first earphone 110,
Two side faces 112 and third side 113 are provided with sound acquisition module, correspondingly, the first side 121 of the second earphone 120,
Second side 122 and third side 123 are provided with sound acquisition module.
In this case, if user begins to send out voice signal, then for the first earphone 110, third side
The intensity of sound of the collected sound of sound acquisition module set by face 113 can be greater than sound set by first side 111
The intensity of sound of the collected sound of acquisition module, and the collected sound of sound acquisition module set by first side 111
Intensity of sound again can be greater than second side 112 set by the collected sound of sound acquisition module intensity of sound.It is based on
Foregoing manner, the first earphone can be determined according to the intensity of sound of multiple sound acquisition modules sound collected sound come
Source direction.
Wherein, if the acoustic environment around the first earphone and the second earphone is complex, it would be possible that will cause multiple sound
The intensity of sound of sound acquisition module sound collected is approximate, to be unfavorable for distinguishing sound source.It is so used as a kind of mode,
First earphone can to multiple earphones sound-content entrained by collected voice signal identify, for the sound of carrying
The identical multiple voice signals (being acquired by multiple sound acquisition modules) of sound content further judge intensity of sound.
Step S330: the voice signal of the first direction based on second earphone and the voice letter of second direction
Number, obtain the source direction of the second earphone voice signal collected.
The mode in sound source direction is obtained similar to the first earphone, the second earphone can also come true in the same way
The source direction of fixed collected sound.
Step S340: the source direction of judgement the first earphone voice signal collected and the second earphone institute
Whether the source direction of the voice signal of acquisition meets setting condition.
As a kind of mode, the transmitting voice signal electron equipment that the first earphone can only issue user, to mention
Before filter out the voice signal that other directions transmit, and then mitigate the data volume of required processing when subsequent noise reduction process, mention
Rise whole voice transfer speed.So in this process, electronic equipment can identify first side 111 shown in Fig. 6,
The intensity of sound of the respective set sound acquisition module sound collected of second side 112 and third side 113.
Wherein, as a kind of mode, imposing a condition includes that sound acquisition module set by third side 113 is collected
The intensity of sound of sound can be greater than the intensity of sound of the collected sound of sound acquisition module set by first side 111, and
The intensity of sound of the collected sound of sound acquisition module set by first side 111 can be greater than set by second side 112 again
The intensity of sound of the collected sound of the sound acquisition module set.If meeting the setting condition, the first earphone, which can be determined that, to be adopted
